The Rasputin Banana is when you use shattered glass from fine glass to slice 3 to 5 of the veins on your penis and shout "Для России!" (Translation: "For Russia!" ) and proceed to rail your boyfriend or girlfriend in the ass until they shit themselves using nothing but dick blood for lube.

I picked up this chick at the bar and she told me she wanted to do something extra kinkytonight so I gave her the Rasputin Banana.
